Advantages and Disadvantages of Steel, Polyester and Polypropylene Strapping
Strapping is the process of banding together a package to secure and contain the load inside for transportation. The practice of strapping is common in industrial packaging and there are many different types of straps available in the market. Each and every one of them has different characteristics and applications too.
Here are some of the most popular types of strappings with their advantages and disadvantages:
Steel strapping is probably the oldest tensile strapping method still available today. It was actually designed for heavy duty packaging on an industrial level and is still used by many organizations. However there are some drawbacks of steel strapping that are slowly making it obsolete. You can see the same from the below advantages and disadvantages.
- It is strong and works well with heavy duty packaging
- It is available in a variety of different sizes, length, width and weight categories
- It has been around for ages and has built a reputation of trust among the industrial workers
- It is sturdy and heavy which is not ideal for gross weight of the packaging
- More weight means that the fuel cost increases
- It cost a lot more expensive than its alternatives
- Application requires special tools or in some cases heavy machinery
- It has sharp edges which are dangerous for workers without safety gear
- Environmentally unfriendly as it is costs a lot to recycle steel
Polyester strapping is probably the best option available in the market right now. It is an all round best in every category, whether it is light packing or heavy duty packing.
If you are looking to purchase polyester strapping then there no better place to get it from than Shippers Europe. They provide the best quality industrial polyester straps.
- It is as strong as steel straps but lighter in weight
- Reduced weight means reduced fuel cost
- It is a high tension strap and it has the ability to retain the tension for longer period of time
- It is water resistant and also rust resistant
- Despite having the same applications it costs nearly 25% less than steel strap
- Its application is quite simple and can also be applied using hand held tools
- It is safe to work with as it has dull edges and does not require the worker to wear special safety gear
- Environmentally friendly as it is plastic and can be recycled easily
- Its elasticity is low
- It is a bit more expensive than polypropylene, especially if you want to use it for light packing
Polypropylene is another type of plastic strap that is a popular choice for light weight packing.
- It is the cheapest strapping material available in the market right now
- It is light weight which is ideal for light packaging
- It has high elongation
- Its application is easy and can be performed directly by hands
- Very safe to work with
- It is not susceptible to any weather condition
- Environmentally friendly and very easy to recycle
- It cannot retain tension for very long
- Can only be used for light weight packing
As the above comparison proves, polyester strapping is the best option among the three popular choices. Although polypropylene comes close regarding the advantages, but it has its limitations which hold it back. The steel on the other hand seems outdated and a useless option as it can easily be replaced by polyester strapping in all its applications.
